Abstract

A method of controlling a gas turbine engine to reduce emissions levels when demand for power from the gas turbine engine is reduced, is disclosed. The method provides a series of operating modes for a gas turbine combustor (300) through which fuel is staged to gradually increase engine power, yet harmful emissions, such as carbon monoxide are kept within acceptable levels.
